that the obstructions lodged upon the shovels V will be removed as thecultivator is traveling across the field. 7

A still further object of the invention is to provide a deviceof thischaracter which is extremely simple in construction. eflicient inoperation, and one which can be manufactured at a very small cost.

l/Vith invention resides in the novel features of con struction,formation, combination and arrangement of parts to be hereinafter morefully described, claimed and illustrated in 25 the accompanying drawing,in which Figure l is a side elevation of the device.

Figure 2 is a top plan view.

Figure 3 is a sectional view on line 83 of Figure 1.

Referring to the drawing, 1 designates the beam of a conventional formof two row cultivator, the rear end of which is curved downwardly andhas fixed thereto the usual shovels 2. v

A clamp 3 is fixed to the innermost beam of the cultivator and serves tosecurely hold the forward end of a bar 4. clamped to the beam. The bar 4is offset laterally with respect to the beam 1 and extends diagonallyacross the rear face of a'rectangular sheet metal fender 5, and to whichit is secured in any approved manner, said bar having a bearing 6, thepurpose of which will appear later.

The cleaner comprises a hub 7 having a plurality of radialarms 8 formedintegral therewith,the free ends of which are pointed, as at 9, in orderthat they will more readily penetrate the earth. The hub is providedwith a reduced axle 10 which rotatably en- Another object of theinvention is to pro these and other objectsin view, this gages a bearing11 formed in the fender 5 and the bearing 6 formed in the bar 4;. Thisaxle is threaded as at l2, forlreceiving the V nut 13. It: will thus beseen that the axle is rotatably mounted in'order that when thecultivator is drawn across thefieldthe hub can freely rotate as thepointed ends of the v arms successively penetrate the earth.

Frequently stall-1s and weeds will be caught between a pair of theshovels, thus retarding the free movement of thecultivator...

It has heretofore been necessary to stop the cultivator and remove theseobstructions. This objection is eliminated by the applica 7 tion of thecleaner, since it will be obvious that as the cultivator is in motionrotary movement will be impartedrto the cleaner and the arms 8 willforce and lift the obstructions from between the shovels in order thatit will not be necessary to stop the cultivator when the shovels becomeclogged.

While the device is primarily designed for use in connection with tworow cultivators, it will be of course understood that it is not limitedto such use, since it will effectively operate in connection with asingle row cultivator.

From the foregoing it is thought that the construction, operation andmany advantages of the herein described invention will be apparent tothose skilled in the art, without further description and it will beunderstood that various changes in the size, shape, and proportion andminor details of construction, may be resorted to without departing fromthe spirit or sacrificing any of the advantages of the invention.

What is claimed is V 1. The combination with a cultivator ineluding abeam and shovel,of a bar secured to the beam and having its fixed endoffset laterally and extended rearwardly and downwardly in spacedrelation to the shovel, said bar being provided with a bearing, a fendersecured to the bar and provided with a bearing registering with thebearing in the bar, and a cleaning device mounted for r0- tation on theinner face of the fender and including a hub having arms radiatingtherefrom, said hub being provided with an (ilk to the forward portionof the beam and having its fixed end offset laterally and extendedrearwardly and downwardly in spaced relation to the shovel, asubstantially rectangular fender plate secured to the inner face of thebar, said bar and fender plate being pro-' vided with alined bearings,and a cleaning device mounted for rotation on the inner face of thefender and including a hub having arms radiating therefrom and providedwith po nted terminals, said hub belng provided with a reduced axlefitting within the alined bearings, and a fastening device engaging theaxleand bearing against the outer face of the bar.
